(Phys.org)—Native American hunter-gatherers living more than a thousand years ago in what is now northwestern California ate salmon, acorns and other foods, and now we know they also smoked tobacco—the earliest known usage in the Pacific Northwest, according to a new University of California, Davis, study.

"The study demonstrates that was part of the northwestern California culture very early ... shortly after the earliest documented Pacific Northwest Coast plank house villages," said the study, published in the .

Testing organic residues extracted from pipes, researchers from the UC Davis Department of Anthropology and the Fiehn Metabolomics Laboratory of the UC Davis Genome Center confirmed was smoked, and likely grown in the region, by at least A.D. 860.

Perhaps more importantly, the researchers say that additional studies may help them better understand the origins of and the human management, geographic range extension and cultivation of tobacco. Indeed, as part of a second study, the authors have recently detected nicotine in ancient pipes from an 800-year-old site in the modern city of Pleasanton, Calif.

Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the Coast. It was unclear, for example, whether European traders had brought tobacco to the area much later, or if some other plant had been smoked in the pipes, Tushingham said.

o Battery power may turn out to be a transition technology. Cost reductions have been slow in coming, and Tesla needs a 30% improvement in order to build the $35,000 Model 3 it has promised for 2017. Toyota’s recent move was eye-opening. It is allowing a battery-supply deal with Tesla to expire and instead will redouble its work on hydrogen fuel cells. The cost of fuel cells is coming down faster than batteries and fuel cell proponents believe drivers will prefer a relatively rapid refuel with hydrogen to waiting hours to recharge their batteries.

Back in the movie wasteland of last January, no one could have guessed what a bounty of good films the year would bring. Not just good films, but several that measure up to our idealized notions of what the medium once was. Two candidates for the top of the heap pretty much chose themselves. For sheer entertainment, the clear call is 'American Hustle,' David O. Russell's joyous celebration of 1970s-era con artists and their intricate cons. For innovation-a new theatrical experience born of new technology-'Gravity' whirls in its own orbit. With the understanding that there's nothing to be said against 'American Hustle,' and everything to recommend this screwball comedy for the ages, I think 'Gravity' is the best movie of the year.
